Alberto

As of 29 May 2018, subtropical depression Alberto has been advecting northward, through the southeastern United States. Alberto made landfall yesterday 28 May 2018, along the Gulf Coast, near the Florida Panhandle. Alberto produced heavy rainfall and has the potential for tornadoes, as it pushes north into the Ohio Valley within the next few days. Rain estimates are 3+ inches in several southeastern states.

Below are two static satellite images of Alberto. The first one is the Near-Constant Contrast (NCC), a derived product of the Day/Night Band (DNB). NCC utilizes a sun/moon reflectance model that illuminates atmospheric features, and senses emitted (i.e. city lights) and reflected light sources (i.e. clouds) during the nighttime.  NCC imagery is taken at 0735Z, 29 May 2018, during the full-moon stage of the lunar cycle. Notice the large areal extent of Alberto, engulfing a few southeastern states. Spatial resolution is at 750-meters.

The second image is of the GOES-16 infrared, low-level water vapor imagery (channel 10, 7.3um) at 0737Z, 29 May 2018. Imagery shows the convective, cold cloud tops (cold brightness temperatures, indicated in blue and green colors) of Alberto that can produce heavy precipitation and severe weather. Spatial resolution is at 2-kilometers.
